Hi guys
Basically theres 2 things ,
1 the reflector inside the headlight unit rubs and puts a fine dust coating on the lens
2 there is a power drop from the wire in the loom being to small.
But the forum notes on the headlight upgrade will give you a good idea of what you need.Theres 7 pages so I'd suggest reading it all as there are a few options.
page 2 is a link about getting the unit apart, you have to put it in the oven to soften the sealant, check it often, have rags or tea towels ready to handle it as it is a bit warm, small screw driver to move tabs on joint and wait until the kitchen boss is away for a couple of hours.
Don't get the sealant on anything, causes domestic problems :)
page 3 explains the voltage drop
Theres also a modification to the blocker plate in the low beam ,I did clean out the headlight module first as the low beam was totally covered in dust but after doing the mod I think I would just take the blocker out all together.
Items from auto sparky because he can show you how to wire the relay if you,re not sure
8 metres dual core 4 mm wire
good connectors
soldering iron
2 inline mini fuse holders
2 x 20 amp fuses
2 small relays - I used smaller than the standard car and zip tied them in place as they have no screwmounts.
zip ties- cable ties
I placed the relays under the seat on top of the mudguard
Fuses between battery and relay on the power circuit to bulb and the earth from bulb to battery negative.
when you cut off the wires at the bulb mounts ensure you leave enough to solder onto the new wire
The white and yellow wires are the power circuits at the headlight.
I connected the relay switch circuit to the original wires going to the headlight here so I did not have to modify the loom. This requires a bit more wire but is much simpler than trying to trace the wires through the loom.
Cost about $50
Any questons message me and I'll give you my phone number
Later swagzz
